=Alpha 220 LED Sign=
+
 
+
I am using my Kuro Pro to drive an Alpha 215/220 LED Display I happened to have one of these signs lying around.
+
 
+

<b>220 Full Matrix</b>, (Case 37.7" x 3.8" x 2.9 ") Tricolor

==Install a Serial Port Interface==
+
First you are going to have to install a [[serial port]] interface.  I ended up installing mine to the [[Add a Serial port to the ARM9 Linkstation | serial port on the bottom]], but the serial port on the [[SCON-KIT/_PRO_quick_manual | front]]  is easier and the same.
+
 
+
 
+
I used a board from futurelec, they are dirt cheap, but take forever to get to you
+
 
+
http://www.futurlec.com/Mini_RS232_TTL_3V.shtml
+
 
+
[[Image:ET-MINI_RS232_3V.jpg|200px]]
+
 
+
I used a Quick port RJ-12 jack to interface the sign to the serial port converter
+
 
+
[[Image:RJ12jack.jpg]]
+
 
+
Then I shoved the whole thing in a 2 port Quick port surface mount housing
+
 
+
[[Image:2PSM.jpg]]
+
 
+
==Interface Sign to Serial Port Interface==
+
 
+
I used a standard 6 wire telephone cable meant for a two line phone (a 4 wire one will not work) Plug one end into the sign.  And one end into the Quick port RJ-12 Jack
+
Wire the jack into the serial port board as such<ref>[http://wls.wwco.com/ledsigns/alpha/cable.html Building a Data Cable for Alpha LED Scrolling Signs]</ref>
+
 
+
* Pin 4 of the RJ12 to RS-232 RX.
+
* Pin 3 of the RJ12 to RS-232 TX
+
* Pin 6 of the RJ12 to RS-232 GND
+
 
+
 
+
==Setup the serial port==
+
 
+
You will have to adjust the serial port settings.  I use a script to do this.  My information came from a FAQ on using the Alpha sign with Linux<ref>[http://wls.wwco.com/ledsigns/alpha/AlphaLinux.html Using the Alpha 215C with Linux]
+
</ref>.

# Tell the sign to print the message

$message = `cat /tmp/textfile` ;

====MODE TAG and COLORTAG====
+
The key parts of this are the MODE TAG and COLORTAG, there is full documentation available for this<ref>[http://www.ams-i.com/Pages/97088061.htm Alpha Sign Communications Protocol (pn 9708-8061)]
+
</ref> but here are the pertinant parts.

| <b>MODE TAG</b>

|-
+
||
+
 
+
* a - Regular smooth scroll, right to left
+
* b - Appear. Centers as much of message on screen, waits, and  displays  rest of message in similar manner
+
* c - Appear with flashing.
+
* d - Auto. Randomly picks an effect for each part of the message, as opposed to the message as a whole.
+
* e - Scroll up.
+
* f - Scroll down from top.
+
* g - Jerky scroll from right to left.
+
* h - Jerky scroll from left to right.
+
* i - Wipe up from bottom, covering text.
+
* j - Wipe down from top, covering text.
+
* k - Wipe over from right to left, character by character, not by pixels.
+
* l - Wipe over from left to right, character by character.
+
* m - Scroll up. Same as 'e'?
+
* n - This is doing something weird based on message itself. Will have to investigate.
+
* o - Auto/Random (same as 'd'?)
+
* p - --> CENTER <-- Text appears at sides and squishes content in.
+
* q - <-- CENTER --> Text splits in center and pushed content out.
+
* r - --> COVER <-- New text covers old out to in.
+
* s - <-- UNCOVER --> New text uncovers in to out.
+
* t - Compressed text! Using this mode the sign tricks your eyes into seeing more characters than it is capable  of physically producing. Scrolls right to left.
+
* u - Fast Appear.
+
* v - Medium Appear.
+
* w - Maybe medium-slow appear.
+
* x - Same as 'p'?
+
* y - Same as 'q'?
+
* z - Same as 'r'?
+
* @ - The sign went blank.

+
 
+
==Stock Ticker==
+
I do use the sign for a number of other purposes, to display RSS feeds and weather forecasts.  But the most complicated script is to display a live stock ticker that gets it's data from yahoo.  It then colors the prices green if they are positive/up and red if they are negative/down for the day.
+
 
+
First you should install perl and make
+
 
+
apt-get install perl make
+
 
+
Then install the quote package <ref>[http://www.circlemud.org/~jelson/software/quote quote -- command-line stock quote display]
+
</ref>
+
 
+
wget http://www.circlemud.org/pub/jelson/quote/quote-0.05.tar.gz
+
tar -xvzf quote-0.05.tar.gz
+
cd quote-0.05
+
./configure
+
./make
+
./make install
+
 
+
you may as well install curl and lynx so that you can use them to get content from the web later
+
 
+
apt-get install curl lynx
+
 
+
Lastly here is a shell script to display the ticker
+
 
+
===leddisplay===
+
<pre>
+
# /usr/local/bin/leddisplay
+
#!/bin/sh
+
# Stock ticker symbols
+
#
+
PTE=/usr/local/bin
+
 
+
stocks="  ^DJI ^IXIC ^GSPC "
+
 
+
        quote $stocks | cut -d"(" -f1 |sed 's/^/\x1C9 \x7F \x1C3 /' | sed '/ -/s/:/\x1C1/g' | sed '/ +/s/:/\x1C2/g' > /tmp/textfile
+
        $PTE/alphamon.pl t A  > /dev/alpha

Album - Photo gallery generator which has theme support

MarginalHacks/Album: A HTML photo album generator that supports themes. It takes directories of images and creates all the thumbnails and HTML that you need.

apt-get install album

Dominatrix6.jpg

Dominatrix6

  • Use wget to get and install this theme
  • To use a theme, download the theme .tar or .zip and unpack it.
mkdir /home/httpd/Themes/
cd /home/httpd/Themes/
wget http://marginalhacks.com/Hacks/album/Themes/Dominatrix6.tar.gz
tar -xvzf Dominatrix6.tar.gz
rm Dominatrix6.tar.gz
  • Full resolution images are usually too big for a web album, so we'll use medium images on the image pages:
  • Then call album with the -theme option, with or without -theme_path:
album -medium 33% -theme Dominatrix6 /home/httpd/test/Photos
album -medium 33% -theme Dominatrix6 -theme_path /home/httpd/Themes/ /home/httpd/test/Photos
